Abstract

A breathing assistance system (10) with functionality for detecting the existence of a fault condition may include a pressure detector (42), a flow detector (40) and a fault detection system (46). The pressure detector (42) may take pressure measurements, each measurement comprising a measurement of a gas flow rate in the breathing assistance system (10). The flow detector (40) may take flow rate measurements, each flow rate measurement comprising a measurement of has flow rate in the breathing assistance system (10). The fault detection system (46) may process the pressure measurements and/or flow rate measurements to determine the existence of a fault condition associated with the breathing assistance system (10).
